Application filed January 4, l 8 9 3;

To all whom it may concern;

Be it known that we, ANDREW GALE and EUoHnR TREMBLAY, citizens of theUnited States, residing at Ohicopee, in the county of l-lampden andCommonwealth of Massachusetts, have made and invented certain new anduseful Improvements in Swivel-Flows, of which the following is aspecification.

Our invention relates to such plows as are prov ded with what is knownas a jointer, or a knife, and more particularly to the means and methodwhereby such jointer and knife are combined with the other parts of theplow. The object of our invention is to make the 1 olnter morepracticable bygiving to it a firmer and steadier supportlthan is usuallydone; to make the jointer adjustable vertically without changingmaterially the horizontal distance between the point of the plow andthat of the ointer; to connect the jointer and footlatch by mechanismfirmer, stronger and more compact than that used in our patent of June4, 1889; to cover and guard the gearing from sod and other chokingmaterial; and to pro-- vlde means for connecting and adjusting the knifewhen used Without removing or disturbing any part except the jointer andits support.

The following is a specification of our in--.

ventlon, reference being had to the accompanying drawings, in which iFlgure 1 is a side elevation of a detached portlon of the land-side orstandard of .a swivel plow, showing our improved apparatus for 5supportlngandoperatingthejointer. Fig.2is a plan of thefoot-latchdetached and inverted. Flg. 3 is an elevation of the larger endof theomter-arbor gear. Fig. f is an elevation of the larger end of thefoot-'latch-spindle gear. Fig.

e 5 1s a side elevation of the upper or beam plateof the adjustableshank. Fig. 6 is a side elevatlonof the lower or hearing plate of the adustable shank. Fig. 7 is a cross-section of the two plates last namedcombined and taken 5 through line 25-26. Fig. Sis a side elevation ofthe knife. Fig. 9 is an end elevation of the gearing guard. Fig. 10 is aside elevation of the last named, and Fig. 11 is a side elevation of aswivel plow, provided with Serial N5. 495,684. (No model.)

our 'impro'ved attachments, the handles, footlatch, mold-board, andpoint being removed.

'ner, except that we provide the forward or main prong thereof with abearing 2, through which passes the spindle 3. This spindle also 50passes through another bearing 4.. in the rear or handle prong ofthejstandard. The rear end. of spindle 3. is bent nearly at'a rightangle,so as to pass downward through slot 5 of the foot-1atch cam 6. Weprovide the collar 7. and make the same fast on spindle 3. in rear ofbearing 2, and in front of the same bearing we provide and make fast thegear 8; the collar and gear so arrangedp'ermit free rotation of thespindle but prevent its moving 7o lengthwise in its bearings. We furtherprovide the forward prong of standard 1. with a socket 9,in whichrotates rather loosely the rear end of the jointer arbor 10. 'We furtherprovide and make fast on arbor 10. the gear '11, which meshes into gear8; these gears,

lniore'or less without unshipping or disturbing the operation of thegears. We provide a jointer 12 which is attached to the arbor 10 by bolt13. or by any other suitable means. To support arbor and jointer 10 and12 and render the latter vertically adjustable we provide what we termthe shank, composed of an upper or beam plate 14, in which is slot 15,and a lower or bearing plate 16,'in which is 0 slot 17. These two platesare connected and firmly bound together, by the bolt 18. Plate 14 ismade fast to beam 19, by suitable means, as shown while through thebearing in plate 16. passes the arbor 10 as shown.

To hold arbor 10 in its socket and bearing we provide and make fast onthe arbor the shoulder or collar 20. To protect gears 8 and 11 from sodand other choking matter, we provide the shield or guard 21, of whichthe front portion is so hollowed and pronged as to cover gear 8. andpass up astride the lower half of arbor 10. We make the rear part ofsuch guard forked so as to pass a limb on either side of the standard 1,whereon it is made fast by bolt 22;

For ground not adapted to the use of a jointer we provide a knife 23, soconstructed as to be readily connected to plate 14; heretofore to usethe knife it has been necessary, not only to unship the jointer but toprovide a new and separate device for making the knife fast; by ourdevice the shank plate 14 becomes an adjustable socket wherein the knifeis held by bolt 18.

Having connected the jointer and foot-latch by the means abovedescribed, we make the gears S and 11 of such proportions that when thefoot-latch 24. is turned from side to side to lock the mold-board, thejointer is at the same time and by the same movement of the foot-latchturned and held fast in the same relative position as the moldboard.

The advantages of our invention are that the mechanism is firm andcompact. As heretofore used the jointer arbor has been much longer thanours, passing back and through the main prong of the standard; and beingwithout our shank or forward support, it was often sprung and bent outof position, rendering it unfit for use. \Ve obviate this by the shorterarbor and shank support; again the point of the jointer has usually beenraised or depressed by moving the arbor back or forward in its inclinedhearing, so that the point of the jointer would be at one time almostvertically over the point of the plow, while at another time it wouldproject far in advance ness and steadiness not heretofore attained.

The utility of the guard 21 in covering and protecting the gears 8. and11 from sods and other choking matter is obvious. It 1s apparent thatthe shank may be made in one piece and do excellent work, but it wouldnot have the adjustable property that we give it. It is likewiseapparent that socket 9. might be made separately from the standard 1.and attached directly to the beam, but this would create unnecessaryparts and tend to greater expense and weakness in construct on.

vWhat We claim as our invention 1s- 1. The guard 21, the lower part ofwhich Is forked and arranged astride the standard 1, whereto it is madefast by bolt 22,-th e forward and upper part of said guard being sohollowed and formed as to protect gears 8 and 11 from sods and otherchoking matter-as specified.

2. The standard 1 provided with the bearings 2 and 4t. and socket 9. incombination with the spindle 3, foot latch 24:, gears, 8 and 11, arborand jointer 10 and 12, shank plates 14 and 1G, and beam 19, allsubstantially as shown and described.
